Holding a cell phone against your ear or stalling it in your pocket may be hazardous to your health．

       This paraphrases a warning that cell phone; manufacturers include in the small print that is often tossed aside when a new phone is purchased．Apple, for example, doesn't want iP hones to come closer to you than 1．5 centimeters; Research In Motion, Blackberry's manufacturer, recommends 2.5 centimeters．

       If health issues arise from cell phone use, the implications are huge．Voice calls - Americans chat on cell phones 2．26 trillion minutes annually - generate $109 billion for the wireless carriers．

       Devra Davis, an epidemiologist who has worked for the University of Pittsburgh, has published a book about cell phone radiation, "Disconnect." The book surveys scientific research and concludes the question is not settled.

　　Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population.

　　"Most cancers have multiple causes," she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer.

　　Children are more vulnerable to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid. No studies have yet been completed on cell phone radiation and children, she says.

　　Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiofrequency radiation had damaged DNA in their brains.

　　Ms. Davis recommends using wired headsets or the phone's speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen.

       B．American cell phone manufacturers benefit greatly from their products

       C．Scientists have found the connection between brain cancer and ceil phone

       D．Cell phone should be banned because of the increase in brain cancer

The train was already half an hour late. I had to arrive in Vienna at 7:15 in time to catch the 7:20 train to Paris, but there was no hope of that now. I told my problem to the conductor (列车员). He advised me to get off two stops before Vienna Station and take a taxi. When the time came, he even helped with my bag. He wished me good luck as I jumped off. A few minutes later I was racing towards the center of the city in a taxi. It was almost 7:25 when we stopped outside the station. I paid the driver quickly, picked up my bag and hurried inside. “Paris train?” was all I had time to say to the official I saw. You can see how I felt when he pointed to a train that was just moving out of the station.
